HEX to OKLCH: #FFFFE0

Also known as: CSS lightyellow

#FFFFE0 → oklch(0.992 0.040 107.1)

Values are shown at full precision, so converting back gives exactly #ffffe0. The rounded form is what you normally paste into CSS.

Step-by-step math

Every number below is computed from the input, nothing is looked up.

1. sRGB → linear

R: 255/255 = 1.00000 → 1.000000  (((x + 0.055) / 1.055)^2.4)
G: 255/255 = 1.00000 → 1.000000  (((x + 0.055) / 1.055)^2.4)
B: 224/255 = 0.87843 → 0.745404  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.986902
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.972657
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.839610

3. cube root

l′ = ∛0.986902 = 0.995615
m′ = ∛0.972657 = 0.990801
s′ = ∛0.839610 = 0.943393

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.99201
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.01184
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.03846

5. Oklab → OKLCH

C = √(a² + b²) = 0.04024
H = atan2(b, a) = 107.111°
L = 0.99201

6. OKLCH

oklch(0.99201 0.04024 107.111)
rounded: oklch(0.992 0.040 107.1)
